  • Yb3+/Er3+-codoped oxyfluoride glass ceramics were prepared by the high temperature melting method, and a suitable fusing temperature(1 100 ℃) and annealing temperatures(440 ℃, 480 ℃) of the rare-earth-doped glass ceramics were determined. Experiments show that the transmittance of the host glass is 85%, but the transmittance drops evidently and there are characteristic absorption peaks of rare-earth ions when the host glass is doped with Yb3+/Er3+ ions. With 980 nm laser diode(LD) excitation, the purple emission peak at 410 nm, green emission peak at 532 nm and 546 nm and red emission peak at 656 nm corresponding to 2H9/24I15/2, 2H11/24I15/2, 4S3/24I15/2 and 4F9/24I15/2 transitions of Er3+, respectively, were simultaneously observed at room temperature. The effects of Yb3+/Er3+ in mol concentration ratio and different concentrations of Er3+ ion on the intensity of up-conversion luminescence was studied. The experiments show that the up-conversion luminescence intensity is up to maximum value when the concentration ratio of Yb3+/Er3+ is 4∶1 and concentration of Er3+ ion is 1.5% in mol concentration. According to the relationship between the pump power and luminous intensity, the four up-conversion luminescences are verified to be the two-photon process. Energy transfer was used in discussing the up-conversion mechanism and the pertinent up-conversion mechanism was proposed.
